Another IPCC modeling failure – so THAT’s where the atmospheric methane went

From Oregon State University – Scientists discover carbonate rocks are unrecognized methane sink CORVALLIS, Ore. – Since the first undersea methane seep was discovered 30 years ago, scientists have meticulously analyzed and measured how microbes in the seafloor sediments consume the greenhouse gas methane as part of understanding how the Earth works. The sediment-based microbes…

The ‘methane hotspot’ identified in the Four Corners area of the U.S. Southwest can be fixed with some preventative maintenence

Study period predates the widespread use of hydraulic fracturing. | One small “hot spot” in the U.S. Southwest is responsible for producing the largest concentration of the greenhouse gas methane seen over the United States – more than triple the standard ground-based estimate — according to a new study of satellite data by scientists at…

Researchers at Brazil's National Institute for Space Research calculated that the world's largest dams emitted 104 million tons of methane annually and were responsible for 4 percent of the human contribution to climate change.

Methane – damned if you do, dammed if you don’t

Drowned tropical forests release too much methane Eric Worrall writes: A new study performed in Laos suggests that building Dams in tropical locations exacerbates climate change. According to Scientific American; “In Asia, Africa and South America, … , masses of methane are produced from dams by the drowning of tropical forests in them. As long…

Cornell hypes on methane as a ‘climate boogeyman’

Through the years, we keep hearing that methane, much like Trenberth’s missing heat, is going to jump out and get us. Usually, the panic about the “methane bomb” from frozen ocean floor methane hydrates or methane from melting Arctic tundra. Now, they are taking on methane as a danger from natural gas production, and suggesting…

Methane: The Irrelevant Greenhouse Gas

Water vapor has already absorbed the very same infrared radiation that Methane might have absorbed. Guest essay by Dr. Tom Sheahen Q: I read that methane is an even worse greenhouse gas than carbon dioxide, and cattle are a big source of methane emissions. How are they going to regulate that? Not just cattle, but…

Permafrost fear

From Florida State University  and the department of we’ve heard all this before comes this story Researchers: Permafrost thawing could accelerate global warming TALLAHASSEE, Fla. — A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which…
